Portable Computer Integrated Projection Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of portable computers with projecting functions is hindered by the need for multiple transmission cables to connect them to external projecting devices, leading to inconvenient operation.
Innovation Solution
A portable computer design featuring a main body, a display module connected via a pivot that can rotate relative to the main body, and a projection module disposed on the marginal surface of the display module, allowing for built-in projection capabilities without external devices and incorporating anti-skid members for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable computer is connected to an external projecting device, then projection function is achieved, but multiple transmission cables are needed which makes operation inconvenient
Solution Approach 1:
The patent combines the projection module directly into the portable computer's display module, merging two previously separate devices (computer and projector) into one integrated unit. This eliminates the need for multiple transmission cables and external projecting devices, directly resolving the contradiction by improving ease of operation while reducing device complexity.
Solution Approach 2:
The display module is designed to perform multiple functions: it can rotate relative to the main body for different viewing angles and simultaneously functions as a projection module. This multi-functionality allows the single integrated component to replace both the display and external projector, eliminating cable connections while maintaining projection capability.
2Adaptability or versatility
If the display module is rotated relative to the main body, then flexibility in positioning is improved, but structural complexity increases
Solution Approach 1:
The pivot structure is integrated into the display module assembly rather than being a separate component. The display module and projection module share the same rotating structure, so the pivot serves dual purposes: enabling display rotation and positioning the projection module. This merging reduces overall structural complexity while maintaining positioning flexibility.

AI summary
A portable computer with a projecting function includes a main body, a display module, a pivot, and a projection module. The display module is connected to the main body via the pivot and capable of rotating relative to the main body. The projection module is disposed on the pivot for projecting the information of the main body. The portable computer is, for example, a laptop computer, or a tablet computer.
